| Research Abstract |
Kinetic microstructure change in the membrane of SrCo_<0.8>Fe_<0.2>O_<3-δ> under the oxygen chemical potential gradient at 1173 K was experimentally observed in this study. From the experimental results, it was found that microstructure of the membrane drastically changed by the oxygen permeation through the membrane. Although this study also tried to estimate the microstructure change by calculating the divergence of the ionic flux through the membrane, it was difficult to obtain the calculated results.
